Question

I am developing a code first web app in Visual Studio 2012 Express.

I use this connection string in the web.config:

Answer 1

Add this code to Global.asax.cs. This will makes sure that your database is always Initialized before any other executions. Also make sure its the first registration in Application_Start()

if (!WebSecurity.Initialized)
                WebSecurity.InitializeDatabaseConnection("DefaultConnection",
"UserProfile", "UserId", "UserName", autoCreateTables: true);

Get rid of Filters/InitializeSimpleMembershipAttribute.cs or just comment the code inside, in case you would like to go back to it.

Remove [InitializeSimpleMembership] at the top of AccountController.cs

Also if you haven't already enabled migrations, i would encourage you do so. That way, you can do your seeds in Configuration.cs created inside the Migration folder when you run Enable-Migrations
